The Anne Arundel County chapter of the NAACP led a rally Thursday night for a fatal shooting victim because his family said it believes the killer got away scot-free.

Kendall Green was shot and killed in September 2013 by Matthew Pinkerton as Green tried to enter Pinkerton's home in Glen Burnie. Green's mother, Felicia Carroll, said her son was in a relationship with Pinkerton's wife and that he went to their home to talk to her.

Citing police reports, Carroll said witnesses said Pinkerton used a racial slur repeatedly before shooting her son.

"My son was murdered. It was a senseless killing," Carroll said. "I don't know what the truth is that night. I just know that my son is gone. I do know that he was called the N-word more than one time."

Pinkerton was charged with second-degree murder and requested a jury trial. But after the prosecution rested its case, Judge William Mulford granted the defense's request for an acquittal. Pinkerton walked free, and the jury never got to decide the case.

Those hoping for justice for Green took to the streets of Annapolis on Thursday.

"We believe that Judge Mulford made a serious mistake when he did not allow a jury to decide whether or not an individual was guilty of a crime. We believe this was a racial crime," said rally organizer Carl Snowden.

The NAACP is involved in the case and has organized several rallies in support of Green's family. It wants the Department of Justice to take a look at the case and consider federal hate crime charges. The group has the support of four members of Congress who sent a letter to the Justice Department on its behalf.

"He called him the N-word three times before he shot him, and it takes hatred in this day in age, in this melting pot that we call America, to say that and then shoot him," Carroll said.

Carroll said Mulford wouldn't allow that evidence in the courtroom and said she and advocates of the case will do what it takes to make sure justice is served.

"Justice, to me, would ensure that the law is carried out equally for everyone and that there are no prejudices involved in carrying out that law," said Anne Arundel County NAACP chapter president Jacqueline Boone Allsup.
